용도 & 기능
Their primary roles focus on water level monitoring and safety regulation:
- Real-Time Level Detection: Sense the presence or absence of water at specific points (예를 들어, low, medium, high levels) inside boilers/steam generators.
- Control Signal Transmission: Send electrical signals to a water level controller when water reaches or drops below target thresholds, triggering automatic water replenishment or system shutdowns.
- Hazard Prevention: Eliminate risks like dry firing (no water in the boiler, which causes equipment damage) or overflow (excess water disrupting steam production).
Key Features
- Corrosion-Resistant Build: Made of 304/316 스테인레스 스틸 (or heat-resistant alloys) to withstand high-temperature, high-pressure, and alkaline/acidic boiler water.
- High-Temp Insulation: Equipped with ceramic (or PTFE) insulation segments to isolate the electrode from equipment bodies, ensuring accurate signal transmission.
- Threaded Installation: Standard threaded bases enable quick, secure fitting into boiler walls or water tanks (compatible with most equipment ports).
- Fast Response: High-sensitivity probe tips deliver near-instantaneous level detection, minimizing delays in control system reactions.
장점
- Harsh-Environment Reliability: Performs consistently in high-temperature/high-pressure conditions (unlike float-type sensors, which may jam or degrade).
- Low Maintenance: Simple, moving-part-free design reduces cleaning/replacement frequency (durable materials resist wear).
- Cost-Effectiveness: More affordable than optical/ultrasonic sensors while meeting core safety/control requirements.
- Multi-Point Precision: Targeted probe placement allows accurate monitoring of multiple water level points (예를 들어, low-level alarms, high-level cutoffs).
응용 시나리오
Widely used in equipment requiring precise water level control:
- Industrial Boilers: Steam/hot water boilers for factories, power plants, or large-scale heating systems.
- Steam Generators: Commercial/industrial units (예를 들어, for food processing, 멸균, or laundry equipment).
- Pressure Vessels: Water-storage pressure vessels and heat exchangers.
- Commercial Heating Systems: Large hot water systems (예를 들어, in hotels or hospitals).
Key Attributes
- 재료: 304/316 스테인레스 스틸 (probe) + high-temperature ceramic/PTFE (insulation).
- Temperature Tolerance: Up to 200℃–250℃ (matches standard boiler operating temperatures).
- Pressure Rating: Compatible with 10–15 bar (standard boiler working pressure).
- Mounting: Threaded (예를 들어, G1/2, NPT) for seamless integration.
- 길이: 맞춤형 (100mm–500mm+) to fit different tank/boiler depths.
Summary
Boiler water level electrode probes are non-negotiable safety and control components for heating/steam equipment. Their durable construction, fast response, and precise sensing ensure reliable water level monitoring—preventing damage, maintaining efficiency, and cutting long-term upkeep costs.
Whether outfitting industrial boilers or commercial steam generators, these probes offer a cost-effective, low-maintenance solution for critical water level management.
